Application filed June B, 1912'. Serial No. 702,516.

To all whom it may concern Be it known that I, AUGUST J. MULLER,

citizen of the United States, residing at Gaclrle, in the county of Logan and State of North Dakota, have invented a new and useful Grain-Elevator; and do hereby de- Clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same'.

This invention relates to a new and useful pneumatic grain elevator.

1t is the primary object of this invention to provide a device of this nature, in which various essentialand desirable features of construction are involved` The mairifeature of the construction is the provision of a hinged gra-in boX having a suctio'ntfan located adjacent the outlet of the box, by which as the grain leaves the box it is drawn into a casio about the fan, and forced through a tube, rom which it is deposited into a grain bin or wagon or the like. Another feature of the construction is the provision of means for tilting the grain bo'x upon its hinged connections with a platform, which is provided with supporting wheels.

Another lfeature of the construction re sides in the means for tilting the outlet portion of the grain tube.

The invention comprises further features arid combination of parts, as hereinafter set forth, as shown in the drawings and claimed.

1n the drawings-Figure 1 is a View in side elevation of the improved grain elevator constructed in accordance with the invent-ion. Fig. 2 is a plan view of the saine.' Fig. 3 is a sectional View longitudinally throughFig. 2 on line 23e-3. Fig. L1 is a transverse sectional view on line 4-4 of Fig. 3.

mounted the usual supporting wheels 3.

Rising from the platform 1 is a' vert-ical frame l, which is braced by the brace bars 5, and stay wires 6. Journaled in bearings of the upper portionfof the frame 4 are two windlass rollers 7 and 8, one end of each of which is provided with a ratchet 9,' to be engaged by a pawl 10, there being a crank handle for each roller whereby the s axne may '.lhe crank handles are vdenoted be rotated. by Ithe numerals 12 and 13.

Hinged to the platform Ai as at 14 is a grain box 15 havingsupporting lors 16, to ass1st in supporting the box and to prevent the-'platform from beiney tilted rearwardly. The bottom of the grain boit is inclined froin all sides (flo\\'1i\iarclly to its center, as shown in Fig. 3, adjacent which point an outlet opening 17 is formed. This opening 17 is closed by a slide door 18, which is mounted in guides 19. Located adjacent the opening 17, from which a spout 20 extends, is a fan casing 21, in which a suction fan 22 is ar ranged. r1`hissuction'fan rotates with the shaft 23, Von which a pulley 21- is mounted. This fan is designed 'to suck the grain into the fan casing, andr force it through the tube 25, which'forms a part of the casing 21. En tending angularly through and sup orted by thedplatforh 1 is a tube 26, the ein??? of which. terminates in a packed socket 28,

which receives the end 29 of the tube 25,

that ,is, when the grain box is in its lowerinost position.

Hinged to the tube 25 as at 30 is atube or spout 31. This tube 81 may be raised and lowered to different heights, to accommodate grain bins or wagons or the like of different heights. Connected at 32 to the tube or spout 31 is a rope 233, which in turn passes about and is connected to the Windlass roller i8, so that when, the roller is rotated the tube or spout 31 may be raised or lowered.

-One end of a rope is connected to the grain box as at 35, while the other end of the ro Je is connected at 3G to the windlass roller By turning the crank of the roller 7, the grain box may be tilted to a position., as Shown at (u.) in dotted lines in Fig. 1, or

disposed vertically as shown at (b) in It will be observed that by the showing V The invention hoving been set forth, what is claimed as new and useful is 2- l. In e-gmin elevator, a portable platform having a, grain tube extending angulerl therethrough. e grain box having an out et and a hinged Connection with the letform, elfen easing carried by the grain gox adjacent the outlet opening and `including e suction fan, the casing having a tube to automatically connect with the angularly arranged tube when the box is lowered upon its hinges, u tube hinged to the engularly arranged tube, and meohanisuus 'for raising and lowering the last named tube und the grain box independently.

2. ln e graan elevator, e portable platform having a grain tube extending enguhirly therethrough with :1 socket at one end and un outlet tube hinged to the other end, u, groin box having an outlet opening hinged to the platform, :L fen easing located ad- :leent the outlet openingr und provided with :L suction fzln, the casing having un extension tube adapted to fit the socket when the grain box is in its lowermost position.

Intestiinony whereof l have signed my muue to this specification in the presence of two euliseribiug Witnesses.
